WARNING: To prevent personal injury or

death, read all safety instructions in the “Safety
Information” section of this manual.

WARNING: To prevent personal injury or

death, shift transmission to park or neutral, set
parking brake, and block wheels before doing
diagnostic or service procedures.

WARNING: To prevent personal injury or

death, make sure that the engine has cooled
before removing components.

NOTE: Engine fluids (oil, fuel and coolant) are a threat
to the environment.

Recycle or dispose of engine

fluids according to local regulations. Never put engine
fluids in the trash, pour fluids on the ground, in sewers
or bodies of water.

Figure 83 Manifold mounting bolts for shielded
tube exhaust assembly

1.

Remove two M8 x 60 bolts securing the shielded
tube exhaust assembly on left exhaust manifold.

NOTE: Install caps (Table 9) to cover all openings. If
plastic caps are not available, cover with tape.

WARNING: To prevent personal injury or

death, do not let engine fluids stay on your skin.
Clean skin and nails, using a hand cleaner, and
wash with soap and water.

Wash or discard

clothing and rags contaminated with engine
fluids.

7.

Turn threaded shaft clockwise to remove EGR
valve.

CAUTION: To prevent engine damage, after removing
the EGR valve, vacuum loose carbon deposits and
debris from inside the intake manifold.

8.

Remove and discard three O-rings.

Intake Manifold and EGR Cooler

NOTE: Before removing intake manifold, remove the
following components:

•

Fuel Filter Housing and Lines

•

VGT

See “Fuel System” and “Electronically Controlled
VGT” sections for removal procedures.

WARNING: To prevent personal injury or

death, wear safety glasses with side shields to
protect eyes. Limit compressed air pressure to
207 kPa (30 psi).

CAUTION: To prevent engine damage, blow out or
vacuum dirt and debris under the intake manifold. This
prevents dirt and debris from entering intake ports
when the manifold is removed.
